Reuters - Iran�s foreign minister said on Sunday that a European mechanism to trade with Tehran fell short and that France, Britain and Germany needed to do more to show their commitment to the 2015 nuclear deal with Iran.

�Instex (the mechanism) falls short of commitments by the E3 (France, Germany, Britain) to save the nuclear deal,� Mohammad Javad Zarif said at the Munich Security Conference. �Europe needs to be willing to get wet if it wants to swim against the dangerous tide of U.S. unilateralism.�
